Description

  The present invention relates to an arrangement configuration of a monitoring camera device and a monitoring camera device including the above arrangement configuration.

  Surveillance camera devices, such as network camera devices, can be used in many different situations, indoors and outdoors, to monitor a site. Surveillance camera devices often include a camera head that is movable within a range of movement for adjustment during installation of the surveillance camera device. This makes it easy to install and adjust the position of the camera head so that monitoring of the surveillance camera device at the site is desirable. The camera head may be additionally or alternatively movable within the range of movement during operation of the surveillance camera. This has the advantage that the line of sight of the camera head of the monitoring camera device can be adjusted during monitoring, and therefore monitoring in the field can be changed. The surveillance camera device may further comprise a plurality of movable camera heads so that the site can be monitored more broadly, or different parts of the site can be monitored by each camera head.

  In many cases, it is desirable to increase the robustness and durability of the surveillance camera device by protecting the inside of the surveillance camera device with a housing. However, the housing design is a complex task because the housing should not interfere with or interfere with the monitoring of the surveillance camera device. Furthermore, the housing should not interfere with the movement performance of the camera head (s) of the surveillance camera device.

  The housing may be further arranged to at least partially prevent viewing inside the surveillance camera device. This is desirable, for example, in research situations where it would be advantageous for a person looking at a surveillance camera device to be prevented from detecting which direction the camera head is facing, or at least to be more difficult to detect. The problem with people in the field to detect where the visible camera head is pointing is based on moving outside of the visible camera head's surveillance by being aware of this and thus preventing this Or at least it can be mitigated. The on-site person discomfort resulting from the feeling of being monitored by a visible camera head can be further reduced. Therefore, it is possible to obtain a more effective and unobtrusive surveillance camera by preventing the inside of the surveillance camera device from being viewed.

  To achieve this objective, US3993866A discloses a housing that encloses a camera. The housing further comprises a transparent cover coated so that the camera is not substantially visible from outside the housing.

  Alternatively, US Pat. No. 6,354,749B1 describes a survey camera housing having an upper housing that houses a pan-tilt mechanism. The camera is carried by a pan / tilt mechanism and extends into the lower transparent housing. A lining material is provided in the lower housing and covers the camera to protect the camera. The lining material covers the camera other than the slot so that the camera lens can capture an image through the lower housing. The shield is fixed to the camera so as to move with the camera and covers the slot of the lining material, and this shield defines one opening of the camera lens. The color of the lining material and the shield is dark so that the position of the camera lens cannot be seen.

  Furthermore, US 5765043A discloses a housing for storing and protecting a device adapted to be continuously directed to an external target object. The housing includes inner and outer window portions that are movable relative to each other as the device moves. The outer window is elongated and oriented around the tilt axis of the device so that a line of sight to the object is always obtained in response to the tilt rotation of the device. The inner window is smaller and extends laterally of the outer window. Since the outer casing or dome is placed on the inner casing or dome, the line of sight to the object is obstructed except when the position of the inner window is aligned with the outer window. In this way, a clear line of sight can be obtained with a relatively small opening.

  US 2005/018074 A1 further discloses an active camera device and robotic device that can protect the camera and camera actuator from the external environment.

  This is accomplished by providing a ball shell type outer body having an opening. The camera is positioned on the outer body and receives an image from the outside of the outer body through the opening. The camera support unit is positioned on the outer body and rotatably supports the camera along a first axis and a second axis that intersect each other at the center of the outer body.

  However, especially when the surveillance camera device comprises a movable camera head, it is necessary to further improve the protection inside the surveillance camera device and prevent it from being seen inside.

  It is an object of the present invention to provide an improved cover so that the protection and / or shielding of the surveillance camera device is improved. According to the first aspect of the present invention, this and other objects that will become apparent from the following description are achieved by providing an arrangement of a surveillance camera having a camera head movable within a range of movement. . The arrangement configuration includes a housing for covering the inside of the surveillance camera device having an opening for the camera head that provides a free line of sight at any camera head position within the moving range, and is free at any camera head position. A shield that is movably disposed with respect to the housing to shield a part of the opening that is not used to provide a clear line of sight, and the first shield portion and the second shield that are movably disposed relative to each other And a shield that is operable between a compressed state and an extended state by moving the first shield part relative to the second shield part.

  The inside of the surveillance camera device can be effectively covered while providing a free line of sight in the camera head by the shield arranged to be movable with respect to the housing. This makes it possible to obtain a surveillance camera device that is more robust and durable.

  The shield and housing can further prevent viewing inside the camera. This makes it possible to use a transparent cover such as a dome window. Thus, for example, if more light from the field can reach the camera head of the surveillance camera without scattering, refraction and / or reflection by the cover as occurs in the case of a reflective or translucent cover, the surveillance camera device The optical quality of the is improved. A clearer field image can be further obtained.

  The opening of the housing may be larger than the size of the camera head, thereby enabling non-perturbative movement of the camera head within the movement range.

  If camera heads with different diameters can be used with the same housing, a more versatile housing is provided. In other words, this opening gives the possibility to use camera heads with different diameters as long as the diameter is smaller than the minimum width of the opening. Therefore, the monitoring camera device including the arrangement configuration can simplify installation and provide more effective on-site monitoring.

  The first shield part and the second shield part arranged to be movable relative to each other so that the shield can be operated between the compressed state and the extended state, thereby enabling a compact arrangement configuration. Is another advantage. A simple arrangement for covering the inside of the surveillance camera device can also be obtained. Therefore, the inside of the surveillance camera device is protected from external forces such as hitting that can damage the surveillance camera device due to the arrangement configuration.

  Viewing the inside of the monitoring camera device from the outside of the monitoring camera device can be further effectively prevented.

  Problems with movable shields that contact or otherwise cushion components such as the base of the camera head and / or control electronics of the surveillance camera device are further reduced.

  The first shield part of the shield is movable within a range corresponding to the moving range of the camera head in order to adjust the opening in accordance with a free line of sight at an arbitrary camera head position. There may be an aperture defined by the first and second end positions.

  It is an advantage that the aperture can have a size corresponding to the size of the camera head. That is, an effective shielding object is obtained in which the contour of the shielding object can closely follow the outer edge of the camera head. Therefore, the gap formed adjacent to the camera head can be avoided and the shielding of the opening can be improved, whereby the inside of the surveillance camera can be covered more deeply. The inside of the surveillance camera device is better protected by a shield. The shield can further effectively prevent viewing inside the surveillance camera device.

  The opening of the first shield part of the shield is changed from the compressed state to the extended state or the extended state in accordance with the position adjustment in accordance with a free line of sight at an arbitrary camera head position. It may be operable towards.

  The shield can therefore follow the movement of the camera head so that it can effectively cover the interior of the surveillance camera device. Viewing the inside of the surveillance camera device from the outside of the surveillance camera device can be further effectively prevented. Cover the inside of the surveillance camera device at any camera head position within the movement range of the camera head by being operable from the compressed state to the extended state or toward the extended state. A simple and compact arrangement can be obtained. Since the camera head can be moved, the surveillance camera device can monitor the site more effectively and flexibly.

  The shield may be operable to an extended state while the aperture is moving from the first end position to the second end position.

  This enables a compact design of the shield, and prevents formation of a gap in the cover inside the surveillance camera device. Problems with contact or interference between shields and components located within the surveillance camera device can thus be further mitigated. This reduces design constraints inside the surveillance camera, and for example, the components in the surveillance camera can be arranged further away from the center of the surveillance camera device. By preventing a gap formed in the cover inside the surveillance camera device, it is possible to further prevent the inside of the surveillance camera device from being seen.

  The arrangement further includes between the first and second shield portions during movement of the aperture from the first end position toward the second end position such that the shield is in an extended state. A spring member may be included that is arranged for relative movement to occur.

  Thereby, a more compact shield can be realized. A gap is prevented from being formed between the housing and the shield. That is, due to the relative movement between the first shield part and the second shield part caused by the spring member, the second shield part extends beyond the first shield part, and the inside of the surveillance camera device is Covered by a shield. The interior of the surveillance camera device can thus be protected from external forces that can arise from a blow. The opening of the housing can further be effectively shielded so that the arrangement prevents the interior from being viewed from outside the surveillance camera device.

  The spring member moves from the first end position to the second end position so that the stretched state of the shield is established before the opening reaches the second end position. In the initial range portion, it can be arranged such that relative movement occurs between the first and second shield portions.

  This has the advantage that the formation of a gap between the housing and the shield is further reduced.

  The range defined by the first and second end positions may correspond to a camera head movement range of 0-90 degrees, preferably 15-75 degrees.

  The shield can be pivotably attached to the housing, which allows the shield to move relative to the housing.

  The shield and / or housing may be opaque, thereby preventing the inside of the surveillance camera device from being seen. This can make it more difficult for a person looking at the surveillance camera device to detect which of the camera heads is facing. It can be further reduced that the person watching the camera feels confused by being observed by the surveillance camera device. For this reason, the monitoring camera apparatus which is less conspicuous is provided.

  The first and second shield portions may overlap in a state where the shield is compressed.

  Therefore, a more compact shield with a small space required for movement inside the surveillance camera device can be obtained. Overlapping further provides a more robust and durable shield.

  The second shield portion may include a cutout portion disposed such that the shield in a compressed state forms the surface of the continuous outer casing, and the common opening includes the cutout portion and the shield portion. It is defined by the opening of the first shield part. Thereby, in the compressed state, the shield can be further compacted by further overlapping between the first and second shield portions.

  The first and second shield portions can be arranged to be movable with respect to each other by means of a joint, and the first and second shield portions are pivotally connected. Therefore, effective relative movement between the first and second shield portions can be realized.

  The joint may include a pivot stop that defines a maximum pivot angle of the pivotable connection between the first shield portion and the second shield portion corresponding to the extended state of the shield. A gap between the first shield and the second shield can thus be prevented.

  The arrangement further includes a plurality of camera heads each movable within an associated movement range, and the housing further includes each arbitrary camera head position of the associated camera head within the movement range of each camera head. Each of the plurality of camera heads is provided with an opening, the first shield part of the shield is provided with a plurality of openings, and each opening is an arbitrary one of the associated camera heads. The position is adjusted in accordance with a free line of sight for each of the camera head positions.

  Thus, a larger area of the scene can be monitored and different parts of the scene can be monitored by each camera head. A plurality of scenes of the site can be monitored by the monitoring camera device, and a more detailed scene of the site can be obtained from the site.

  According to the 2nd aspect of this invention, the surveillance camera apparatus containing the arrangement configuration mentioned above is provided.

  The functions and advantages of the surveillance camera device are described above with respect to the arrangement. The features described above also apply to this second aspect where applicable.

  It is noted that the invention relates to all possible combinations of features recited in the claims.

  These and other aspects of the invention will now be described in more detail with reference to the accompanying drawings, which illustrate embodiments of the invention.

  As shown in the drawings, the sizes of layers and regions are expanded for illustrative purposes and are provided to illustrate the general structure of embodiments of the present invention. Like reference numbers refer to like elements throughout.

It is a figure which shows the surveillance camera apparatus. FIG. 2 is a diagram illustrating the surveillance camera device of FIG. 1 further including an arrangement 200 of surveillance camera devices according to an embodiment of the present invention. FIG. 3 is an enlarged view and assembly schematic side view of the arrangement of FIG. 2 according to one embodiment of the present invention. FIG. 3 is an enlarged view and assembly schematic side view of the arrangement of FIG. 2 according to one embodiment of the present invention.

  The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate presently preferred embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are not intended to be exhaustive And is provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

  FIG. 1 shows a surveillance camera device 100 comprising a dome window 102 (shown in dotted lines), a mounting base 104 and a plurality of camera heads 106.

  The surveillance camera device 100 according to the embodiment shown in FIG. 1 is shown without the arrangement of the present invention including a housing and a shield for clarity. The arrangement will be described in detail below with reference to FIGS. 2 and 3a-3b.

  According to the embodiment shown in FIG. 1, the monitoring camera device 100 is a network camera device including three camera heads 106. The field of view of the camera head 106 may be spatially separated or overlapped. Multiple camera heads 106 can thus expand the field of view of surveillance camera device 100 compared to the use of a single camera head. The camera head 106 is arranged to capture an image or image stream from the scene. The camera head 106 may be arranged to provide an image or image stream that may be presented separately or stitched together. Each of the camera heads 106 can move within a moving range. The range in which the camera head can move, that is, the angle range is set according to the movement range of the camera head 106. The moving ranges of different cameras may be different, but may be the same. The camera heads 106 can move individually or move in unison. The movement of the camera head 106 can be performed during installation or adjustment of the surveillance camera device 100, for example, to adjust the site (s) monitored by the surveillance camera device 100. The camera head 106 can further move during operation of the surveillance camera device 100 so that an object in the field can be followed, for example.

  Here, the mounting base 104 may have a circular cross section and be rotatable around an axis substantially perpendicular to the circular cross section of the mounting base 104 of the monitoring camera device 100. Thereby, the mounting base 104 can be mounted more flexibly. The mounting base 104 can further be arranged so that the surveillance camera device 100 rotates so that the field of view of the surveillance camera device 100 can be varied.

  According to another embodiment, the mounting base 104 can be fixed to the monitoring camera device 100.

  The dome window 102 is usually made of a transparent material such as a transparent plastic material. In order to protect the surveillance camera device 100, specifically the camera head 106 of the surveillance camera device 100 from external forces, the dome window 102 may be made of a material that is strong enough to withstand a certain amount of impact or impact. it can.

  However, due to the transparency of the dome window, the inside of the monitoring camera device 100 can be seen from the outside of the monitoring camera device 100. A person looking at the monitoring camera device 100 can thereby detect which of the visible camera heads 106 is facing, so that a certain site location is currently monitored by the monitoring camera device 100. There is a possibility to obtain information on whether or not. Therefore, since the person can move out of the field of view of the one or more camera heads 106 in order to avoid being monitored by the monitoring camera apparatus 100, the effect of the monitoring camera apparatus 100 in, for example, research use is reduced.

  Depending on the degree to which a person watching the monitoring camera device 100 can see the inside of the monitoring camera device 100, it may happen that this person feels being monitored by a visible camera head. This can make this person uncomfortable.

  The control electronics 108 that move the camera head 106 can, for example, also be visible from outside the surveillance camera device where attention can be directed. The control electronics 108 may further comprise a light emitting element such as a light emitting diode that may make the surveillance camera device 100 more noticeable.

FIG. 2 shows the surveillance camera 100 according to FIG. 1 further including an arrangement 200. The arrangement configuration 200 includes a housing 202 for covering the inside of the monitoring camera device 100. The housing 202 has openings 204 and 206 of the camera head 106 for obtaining a free line of sight at an arbitrary camera head position within the movement ranges MR ₁ and MR ₂ of the camera head 106. Housing 202 by two parts assembled as a joint is formed between the two parts extending in parallel with the moving range MR _2, it may be formed. This simplifies the manufacture of the housing 202.

  The arrangement 200 further includes a shield 208 movably arranged relative to the housing 202 such that parts of the openings 204, 206 that are not used to obtain a free line of sight at any camera head position are shielded. Including. The arrangement 200 thereby protects the interior of the surveillance camera device 100 and provides a more robust and durable surveillance camera device 100.

  According to this embodiment, the housing 202 and the shield 208 are opaque so that viewing the interior of the surveillance camera device 100 is prevented. By preventing viewing the interior of the surveillance camera device 100, it is prevented or at least more difficult to determine which camera head 106 is facing. Therefore, as described above, the monitoring camera device 100 that is more effective and less noticeable can be obtained.

  The camera head 106 according to this arrangement further includes an anti-reflective coating on the outer protruding end so that it is more difficult to determine the line of sight. The housing 202 and the shield 208 are preferably the same material and / or have the same appearance. The surface structures and colors of the housing 202 and the shield 208 may be the same. The camera head 106 can have the same appearance as the housing 202 and the shield 208.

  The housing 202 and / or shield 208 may further be made of a plastic material such as a polycarbonate / acrylonitrile-butadiene-styrene (PC / ABS) thermoplastic mixture. Metal materials can also be used.

  FIGS. 3 a and 3 b show schematic side views of the arrangement 200 of the surveillance camera device 100, showing the opening 204 of the housing 202. For clarity, the arrangement 200 is shown in both a partially enlarged view and an assembled view. The opening 204 has a lower edge 204a and an upper edge 204b. The lower edge 206a and upper edge 206b of the second opening 206 are also shown in the drawing for clarity.

  The shield 208 further includes a first shield part 302 and a second shield part 304. The first shield part 302 and the second shield part 304 are in a state 306 in which the shield 208 is compressed by moving the first shield part 302 relative to the second shield part 304 (see FIG. 3a). And the extended state 208 (see FIG. 3b) are movably arranged relative to each other. According to this embodiment, the first shield part 302 and the second shield part 304 are arranged outside the first shield part 302 in a state where the second shield part 304 is at least compressed. It overlaps.

The first shield portion 302 of the shield 208 is provided with an aperture 310 which is movable in a range corresponding to the movement range MR ₁ of the camera head. The range is defined by a first end position 312 and a second end position 314, which are shown in FIGS. 3a and 3b, respectively. Free gaze at any camera head position is achieved by the aperture 310 following the movement of the shield 208 and then following the movement of the camera head (shown only in FIG. 2). Thereby, the contour of the mask set by the periphery of the opening 310 can closely follow the periphery of the camera head 106, thereby effectively shielding the opening 204 and covering the inside of the monitoring camera device 100. Therefore, the formation of a gap adjacent to the camera head can be avoided, and the inside of the monitoring camera device 100 can be covered more closely. The housing 202 and the shield 208, that is, the first shield part 302 and the second shield part 304 are opaque in this embodiment, so that it is more effective to look inside the monitoring camera device 100 by the arrangement 200. Is disturbed.

  3a and 3b further illustrate how the shield 208 can be manipulated from the compressed state 306 to the extended state 308 as the aperture moves from the first end position 312 to the second end position 314. Indicates whether or not For completeness, the shield 208 is positioned when the aperture 310 is positioned anywhere between the first end position 312 and the second end position 314 in response to movement of the shield 208. We want to preface moving from the compressed state 306 to the expanded state or toward the expanded state. This makes it possible to adjust the position of the opening 310 of the first shield portion 302 of the shield 208 with a free line of sight at an arbitrary camera head position.

  It is possible to operate from the compressed state 306 to the extended state 308 or toward the extended state 308, thereby covering the inside of the surveillance camera device 100 at any camera head position within the movement range. A compact arrangement 200 is provided. Since the movement of the opening 310 is not interrupted, the camera head 106 can easily move smoothly, and the surveillance camera device 100 can effectively and flexibly monitor the site while covering the inside of the surveillance camera device 100.

  The shield 208 is further operable to the extended state 308 while the aperture 310 is moving from the first end position 312 to the second end position 314. The relative movement of the associated first shield part 302 and second shield part 304 may prevent the formation of a gap in the shield 208 and effectively cover the surveillance camera device 100. A shield 208 with a compact design is further obtained.

  The spring member 316 causes a relative movement between the first shield part 302 and the second shield part 304, and the shield 208 is extended 308 while the opening 310 is moving. That is, the expanded state 308 is reached when the aperture 310 moves from the first end position 312 toward the second end position 314. The above movement can be achieved by moving the camera head 106 of the monitoring camera apparatus 100 including the arrangement 200. That is, the relative movement between the first shield part 302 and the second shield part 304 caused by the spring member 316 causes the second shield part 304 to extend beyond the first shield part 302, That is, the inside of the monitoring camera device 100 is covered by the shield 208. The inside of the monitoring camera device 100 can also be effectively covered thereby, and the inside of the monitoring camera device 100 can be prevented from being seen from the outside.

  The spring members 316 and their arrangement are shown in more detail in the separated enlarged view of FIGS. 3a and 3b. The spring member 316 is disposed on the housing 202 in this embodiment, but may be disposed on the shield 208 in other embodiments.

  A contact portion 317 is disposed on the second shield portion 304. The abutting portion 317 is placed in contact with the movable leg portion of the spring member 316, so that the second shield portion can move relative to the housing 202 against the spring action of the spring member 316.

  The spring member 316 is arranged to control the relative movement between the first shield part 302 and the second shield part 304 during the movement of the aperture 310. While the second shield part 304 becomes smaller, the formation of a gap between the shield 208 and the housing 202 at the lower ends 204a and 206a of the openings 204 and 206, for example, is prevented. 208 is obtained. The relative movement between the first shield portion 302 and the second shield portion 304 controlled by the spring member 316 during movement of the aperture 310 causes the aperture 310 to move to the second end position 314. Prior to reaching, the stretched state 308 of the shield 208 is established, and the aperture 310 reaches the first end position 312 during movement from the second end position 314 to the first end position 312. A compressed state 306 can then be established. This prevents a gap that is not covered by the shield 208 from being formed. By overlapping the casing 202 and the shield 208 of the arrangement configuration 200, the inside of the surveillance camera device 100 can be covered.

Referring again to FIGS. 3a and 3b, according to this embodiment, the range defined by the first end position 312 and the second end position 314 is a 15 to 75 degree camera head travel range MR. Corresponds to ₁ . The aperture 310 is further movable in a range MR ₁ corresponding to the moving range of the camera head, so that a free field of view is obtained at any camera head position within the range MR ₁ . This is advantageous, for example, in a situation where the monitoring camera device 100 including the arrangement configuration 200 is arranged on the ceiling of the room. This moving range can prevent the monitoring camera device 100 from monitoring the ceiling itself. However, the field of view of the camera head 106 may be large enough to see the room from 0 to 90 degrees.

  According to another embodiment, the range defined by the first end position 312 and the second end position 314 corresponds to a movement range of 0-90 degrees. An angle space of at least 90 degrees can be monitored by the camera head of the monitoring camera device 100 covering 0 to 90 degrees.

  It should be noted that the surveillance space of the surveillance camera device can be further expanded by the angular space covered by the field of view of the camera head. As an example, a camera head with a 60 ° field of view, for example, may allow monitoring of the angular space defined by the first end position and the second end position, with an additional 60 °. The additional 60 ° is taken from the field of view of the camera head capable of an additional 30 ° at each end position. Furthermore, as shown in FIGS. 1 and 2, by having three camera heads, the surveillance camera device can cover a horizontal angle of 180 °, for example.

  Other cameras in the plurality of camera heads may additionally have a movement range of 15 to 75 degrees, or alternatively 0 to 90 degrees. As shown in FIG. 1, for example, by supplying three camera heads, at least the entire hemispherical space can be monitored. The field of view of the camera head may be separated or overlapped. Images or arrays of images captured by the surveillance camera device can be stitched together to form a single display image.

  Relative movement of the shield 208 and the housing can be achieved by the shield 208 pivotally attached to the housing 202.

  The first shield portion 302 and the second shield portion 304 are further movably arranged relative to each other by means of a joint 318 that provides a pivotable connection between the first shield portion 302 and the second shield portion 304. Can be done. Therefore, effective relative movement between the first shield part 302 and the second shield part 304 can be realized.

  The first portion 302 and the second portion 304 of the shield 208 in this embodiment are arranged to extend into the corresponding opening fixture 322 of the second portion 304 of the shield 208. Are pivotally connected by means of a joint 318 comprising a plurality of protruding elements 320. The protruding element 320 and the opening fixture 322 provide rotational snap-type engagement.

  The protruding element 320 can further extend beyond the opening fixture 322 so that the protruding element 320 can reach the housing 202. The shield 208 can thereby be pivotally mounted to the housing 202 via the protruding element 320. Thereby, the shield 208 can be movably disposed with respect to the housing 202.

  In other embodiments, the housing can be provided with a protruding element and the shield can be provided with a corresponding opening fixture. One skilled in the art can use other types of arrangements to achieve relative movement of the first and second parts of the shield and / or relative movement of the shield relative to the housing. Will realize.

  The joint 318 includes a pivot stop 324 that defines a maximum pivot angle of a pivotable connection between the first shield part 302 and the second shield part 304. The joint 318 is shown in the enlarged view of FIGS. 3a and 3b. The turning stop portion 324 is disposed in the second shield portion 304 and is arranged so that the maximum relative movement between the first shield portion 302 and the second shield portion 304 is possible. When the maximum relative movement is reached, the swivel stop 324 is arranged to engage the first shield part 302, so that the continuous movement of the shield parts 302, 304 occurs in a consistent manner. Thus, the pivotable connection allows the first shield portion 302 to move relative to the second shield portion 304, which is defined by the pivot stop 324 and the shield 208 is extended. Only the range corresponding to the state 308. This can prevent a gap between the first shield and the second shield.

  The spring arrangement 316 is arranged to cooperate with the joint 318 during the movement of the shield 208. When the opening 310 of the shield 208 moves from the first end position 312 to the second end position 314, the first shield section 302 moves relative to the second shield section 304, and the shield 208 moves. Extend. When reaching the extended state 308 of the shield, the first shield part 302 that coincides with the movement of the second shield part 304 moves continuously. By the movement of the second shield part 304, the contact part 317 is then engaged with the movable leg part of the spring member 316, and the spring member 316 is biased. As a result, when the aperture 310 is positioned at the second end position 314, the spring member is biased and the spring member 316 is initially moved while the aperture 310 is moving in the direction of the first end position 312. Acting on the second shield part 304, and the second shield part 304 moves in alignment with the first shield part 302. The matched movement of the first shield part 302 and the second shield part 304 continues until the second shield part 304 reaches a position corresponding to the compressed state 306 of the shield 208, and the first shield part Subsequent movement of 302 compresses shield 208 until it reaches its own compressed state 306.

  The joint 318 further includes an additional pivot stop 325 that defines a stop pivot angle of the pivotable connection between the first shield portion 302 and the second shield portion 304 corresponding to the compressed state 306 of the shield 208. So that the first portion 302 of the shield 208 does not extend beyond the second portion 304 of the shield 208 in the compressed state 306. This prevents the shield first portion 302 from extending into the interior of the arrangement and coming into contact with components within the surveillance camera device.

  Referring to FIG. 3b, in this embodiment, the arrangement 200 has a first shield portion 302 with a recess 326 so that a stop 328 is formed. In this embodiment, the recess 326 has a thickness such that the combined thickness of the recess 326 and the second shield portion is substantially the same as the thickness of the first shield portion 302, ie, where The first shield part 302 does not include the recess 326. Step 328 thus provides an additional stop angle for the pivotable connection between the first shield portion 302 and the second shield portion 304 in the compressed state 306 of the shield 208. A surface having a substantially uniform thickness is thus provided so that the first shield part 302 and the second shield part 304 overlap in a compressed state 306 (see FIG. 3a). This provides a more uniform outer surface 329 of the shield 208 in the compressed state 306. The force acting on the additional swivel stop 325 in the compressed state 306 is further reduced by step 328.

  The second shield part 304 has a cutout 330 as shown in FIG. 3b. The cutout 330 allows the shield 208 in the compressed state 306 to form a continuous outer envelope surface 331 (see FIG. 3a). A common opening is also defined by the cut-out portion 330 and the opening 310 of the first shield portion 302 of the shield 208. The overlap between the first shield portion 302 and the second shield portion 304 is thereby further increased, and the shield 208 can be made more compact in the compressed state 306.

  One skilled in the art will know that the present invention by no means is limited to the preferred embodiments described above. On the contrary, many modifications and variations are possible within the scope of the appended claims.

  For example, the camera head can be moved in a pan or tilt movement.

  The first shield part 302 can be arranged to move outside the second shield part 304.

  The housing 202 and the shield 208 may be transparent, but this reduces the line-of-sight blocking effect.

  The moving range of the camera head may be 0 to 180 degrees. Thereby, a space larger than the entire hemisphere space can be monitored by the monitoring camera device.

  The apertures and / or openings can be shaped, for example, oval, rectangular, pentagonal, etc., and can be adapted to the outer shape of each camera head.

  Although only the opening 204 and the associated aperture 310 have been described in connection with FIGS. 3a and 3b, the functions of the other two camera head openings shown in FIG. 1 are the same.

  However, in other embodiments, the arrangement can include more than three camera heads, each camera head is movable within an associated range of movement, and the housing further includes a plurality of camera heads. Including an opening, whereby a free line of sight is obtained at each of the arbitrary camera head positions of the associated camera head within the range of movement of each camera head, the first shield portion of the shield having a plurality of apertures Each aperture can be adjusted to a free line of sight at each arbitrary camera head position of the associated camera head.

  According to other embodiments, the arrangement may include a single camera head.

  The camera head may be any type of camera head, for example, a camera head using visible light, IR camera head, or temperature camera head.

  In addition, variations of the disclosed embodiments can be understood and executed by those skilled in the art in practicing the claimed invention by reviewing the drawings, the description, and the appended claims. It is possible. In the claims, the word “comprising” does not exclude other elements or steps, and an infinitive such as “a (a)” or “an” does not exclude a plurality. The fact that certain measures are recited in mutually different independent claims does not indicate that a combination of these measures cannot be used.
